style="text-indent:25px">大家都知道在軟啟動(dòng)器中都會(huì)有一個(gè)R型變壓器，R型變壓器主要是采用取向性高磁導(dǎo)率硅鋼帶制成的，同時(shí)具有體積小、重量輕、效率高、漏磁小等特點(diǎn)得到了普遍的應(yīng)用。軟啟動(dòng)器在控制電路時(shí)需要使用低壓直電流，但是又不能直接使用開(kāi)關(guān)電源，所以在使用時(shí)需要一種隔離電源變壓器，于是軟啟動(dòng)器就看上了R型變壓器了。軟啟動(dòng)器選擇R型變壓器也不是沒(méi)有道理的，下面來(lái)說(shuō)一下使用R型變壓器的好處。 1.效率高 R型變壓器鐵芯無(wú)切割，損失小，并且使用***的材料和緊湊的結(jié)構(gòu)，可以把鐵芯與繞組之間的距離降底，這樣效率可以達(dá)到百分之90以上。 2.無(wú)噪音由于R型變壓器是使用***低損耗的材料，并且具有均勻圓形截面和連續(xù)的繞線，電阻的損耗和產(chǎn)熱都非常的低，磁致伸縮應(yīng)力很容易被吸收，因此在使用過(guò)程中不會(huì)發(fā)出噪音來(lái)。 3.漏磁小 R型變壓器的鐵芯都是繞線極勻衡，因此漏磁是非常小的，在使用過(guò)程中無(wú)需采取防范措施來(lái)防止漏磁的現(xiàn)象。 4.符合安全的標(biāo)準(zhǔn) 由于它的獨(dú)特設(shè)計(jì)，將初級(jí)與次級(jí)的骨架分開(kāi)，并且具有良好的絕緣性。由于阻燃材料制成的互相分離的骨架這樣可以滿足我國(guó)的安全標(biāo)準(zhǔn)淄博科恩軟啟動(dòng)器產(chǎn)品介紹科恩電氣品質(zhì)好、服務(wù)好、客戶滿意度高。</p><div

軟起動(dòng)器就是應(yīng)用較多的控制設(shè)備,軟啟動(dòng)器在不同領(lǐng)域、不同行業(yè)甚至是不同設(shè)備上的應(yīng)用往往也有著極大的不同。1、軟起動(dòng)器在城市雨水排污泵站、污水處理廠中的應(yīng)用雨水排污站的泄水池是雨水、生活污水、工業(yè)污水的集中地，為確保泄水池液位保持在允許的范圍內(nèi)，通過(guò)檢測(cè)泄水池液位來(lái)自動(dòng)控制排污泵組工作以保證污水的正常排放。2、軟起動(dòng)器應(yīng)用于自來(lái)水廠、加壓泵站清水泵主要實(shí)現(xiàn)大功率水泵電機(jī)的軟起動(dòng)、軟停車，重點(diǎn)消除、減弱水錘的危害。當(dāng)液體在管路系統(tǒng)中受外力突然加速或突然減速、或改變流向就會(huì)造成水錘，水錘危害很大，輕則引起管路，系統(tǒng)振動(dòng)，發(fā)出噪聲，重則造成損壞，甚至使泵房被淹。3、軟起動(dòng)器在消防泵控制中的應(yīng)用消火栓泵、噴淋泵是工業(yè)和民用建筑消防設(shè)施的重要消防裝備，其運(yùn)行可靠性極其重要，隨著大中型建設(shè)項(xiàng)目的興建，所配置的消火栓泵、噴淋泵功率、揚(yáng)程增大，傳統(tǒng)的降壓起動(dòng)方式凸顯其缺點(diǎn)，尤其高層建筑水錘危害嚴(yán)重，給設(shè)備運(yùn)行帶來(lái)不安全因素，目前軟起動(dòng)在消防泵控制中得到的應(yīng)用。4、軟起動(dòng)器在在各種類型的深井潛水泵、長(zhǎng)軸泵中的應(yīng)用一般深井潛水泵揚(yáng)程較大，非軟停機(jī)時(shí)水錘現(xiàn)象明顯。

采用矢量控制方式的通用變頻器不僅可在調(diào)速范圍內(nèi)與直流電動(dòng)機(jī)相匹配，而且可以控制異步電動(dòng)機(jī)產(chǎn)生的轉(zhuǎn)矩。轉(zhuǎn)矩控制根據(jù)不同的數(shù)學(xué)算法其功能結(jié)構(gòu)也不相同，如圖所示是一種典型的采用矢量方式實(shí)現(xiàn)的轉(zhuǎn)矩控制功能框圖。先是根據(jù)轉(zhuǎn)矩設(shè)定值計(jì)算出轉(zhuǎn)差頻率，并與變頻器獲得的反饋速度(一般用編碼器PG)或是直接推算的電動(dòng)機(jī)速度相加，在速度限制下輸出同步頻率。很顯然，在轉(zhuǎn)矩控制方式下，速度調(diào)節(jié)器ASR并不起直接作用，也無(wú)法控制速度。轉(zhuǎn)矩控制時(shí)，變頻器的輸出頻率自動(dòng)負(fù)載速度的變化，但輸出頻率的變化受設(shè)定的加速和減速時(shí)間影響，如需要加快的速度，需要將加速和減速時(shí)間設(shè)得短一些。轉(zhuǎn)矩分正向轉(zhuǎn)矩和反向轉(zhuǎn)矩，其設(shè)定可以通過(guò)模擬量端子的電平來(lái)決定，該轉(zhuǎn)矩方向與運(yùn)行指令的方向（即正轉(zhuǎn)和反轉(zhuǎn)）無(wú)關(guān)。當(dāng)模擬量信號(hào)為0～10V時(shí)，為正轉(zhuǎn)矩，即電動(dòng)機(jī)正轉(zhuǎn)方向的轉(zhuǎn)矩指令（從電動(dòng)機(jī)的輸出軸看是逆時(shí)針轉(zhuǎn)）；當(dāng)模擬量信號(hào)為-10～0V時(shí)，為負(fù)轉(zhuǎn)矩，即電動(dòng)機(jī)反轉(zhuǎn)方向的轉(zhuǎn)矩指令（從電動(dòng)機(jī)的輸出軸看是順時(shí)針轉(zhuǎn)）。科恩電氣生產(chǎn)的產(chǎn)品受到用戶的一致稱贊。</p><div

1.電機(jī)軟啟動(dòng)器本身是沒(méi)有短路保護(hù)的，為了保護(hù)其中的晶閘管應(yīng)該采用快速熔斷器，因此我們?cè)谝鶕?jù)軟啟動(dòng)器的額定電流來(lái)選擇快速熔斷器，因?yàn)榈蛪簲嗦菲鏖_(kāi)斷時(shí)間較長(zhǎng)(約為0.1S)，所以不宜用于晶閘管的保護(hù)。 2.當(dāng)我們?cè)谑褂秒姍C(jī)軟啟動(dòng)器時(shí)，使電動(dòng)機(jī)制動(dòng)停機(jī)，主要的原因是由于晶閘管不導(dǎo)通，所以我們?cè)跈z修電動(dòng)機(jī)或線路時(shí)，必須要先斷開(kāi)供電電源，這樣可以使軟啟動(dòng)器與電源之間增設(shè)斷路器
